International Twins Day

During a multiple pregnancy, a woman can give birth to twins - babies that are different from each other, often having different blood types and genders Twins are born with an identical set of genes and have the same face, body, hair and eye color Such kids are a copy of each other In honor of the children, who are surprisingly similar, a zodiac constellation located in the northern hemisphere of the sky was named, and a holiday was established International Twins Day is celebrated on the last Sunday of May every year Children with the same genotype most often appear after the IVF procedure, in women after long-term use of contraceptives and over 35 years of age Exact copies of each other are also born in families in which there were twins in the family of the mother or father Legends are made about the internal connection of such children Twins and triplets have similar habits, gestures and temperaments, even if they were separated in childhood and raised apart from each other Incredible, but true: Twins can have different fathers if a woman has two eggs matured during ovulation, which were fertilized by the sperm of two men The skin color of babies also depends on the race of the parents In a couple where the mother is black and the father is Caucasian, twins can be born with the same appearance, but different skin color Brothers and sisters who are copies of each other and were born within minutes of each other grow and develop synchronously thanks to a strong internal connection In infancy, they communicate in one language they understand, using special gestures and facial expressions This twin communication system is called cryptophasia They feel each other at a distance thanks to a mental connection even in adulthood Incredible but true: Identical twins have the same set of genes This feature complicates the investigation of crimes Using DNA analysis, it is almost impossible to distinguish between biological samples of hair, blood and saliva from twins Scientists note that most often children with the same appearance and genotype are born in Africa Thus, in the Central African Republic, per 1000 pregnancies there are 18 multiple pregnancies, which end in the birth of twins In other regions of the world this figure is noticeably lower In Europe, out of 1000 pregnancies, 8 result in the birth of twins The fewest children with the same appearance are born to representatives of the Mongoloid race Incredible but true: About 1/4 of all twins on Earth are mirror images of each other If one has a mole on the right cheek, then his copy has it on the left If one brother has a dimple on his right cheek when he smiles, the other has a dimple on his left This pattern applies to facial asymmetry, ear shape and teeth shape If one of the mirror twins is left-handed, then the second is always right-handed Children with the same appearance have a greater opportunity to become famous than their equally talented peers It is easier for twins to make a career in cinema, such as Vladimir and Yuri Torsuev from “The Adventures of Electronics”, Vin Diesel from the “Fast and Furious” media franchise and his brother Paul Vincent, who is also an actor Peter and David Paul, widely known for the cult film “Nannies,” both starred in films and engaged in bodybuilding, Igor and Vadim Vernik devoted themselves to theater and cinema Americans of Italian origin Dean and Dan Caten, who look like two peas in a pod, create clothing models for their brand Dsquared2 Maria and Anastasia Tolmachev sing and take part in Eurovision, comedians Valery and Alexander Ponomarenko perform reprises on stage The "quadruplets" Esme, Lisa, Tessa and Bo Ax from the Netherlands work as models The sisters, in addition to performing on the catwalk, film the reality show “Hardenbergse Esmé, Tessa, Lisa en Bo Akse” These and other celebrities, like ordinary brothers and sisters with the same set of genes, celebrate International Twins Day on the last Sunday in May
